DYEmG MACHINE. I

Application led October Our invention relates to certain improvements inthe dyeing maching for which application was filed by us on the 9thv,day of July, l1925, Serial No. 42,520. n i The object of the presentinvention 1s to improve the means of driving the paddles, so as to morethoroughly circulate the dye liquor, and to provide means for supplyingthe vats with dye liquor independently of the means for supplying waterthereto. In the accompanying drawings: Fig. lis a plan view of ourimproved 'dyeing machine; s

Fig. 2 is a longitudinal sectional v1ew on the line 2-2,'Fig. 4;

Fig. 3 is an end view; and Fig. 4 is a transverse sectional view on theline -4-4, Fig. 1.

The vat 1 is elongated and has a curved bottom 2. Partitions 3 dividethe vat into a series of compartments. The artitions are perforated vtoallow the dye iquor to circulate through all of the compartments,

but the materialto be dyed is confined in its particular compartment.

In the bottom of the vat are perforated sections 4, under which areperforated steam pipes 5. In the present instance two pipes are shown,one extending from one end of the vat, and the other extending from theopposite end thereof. The steam heats the dye liquor in the vat.

The coloring matter is introduced into the vat by means of small pipes6, which extend diagonally from each of the vats to a partition. At thispoint each two branches 7 one kdischar 'ng into one compartment, and theother d1scharging into an adjoining compartment, as shown in o Fig. 2.By this construction the coloring matter is introduced into the vat insmall quantities at different points. At the outer end of each pipe is avalve 8, and above the valve is a funnel 9.

On each end of the vat is a bearing 10, and on the central partition `isa bearing 11. A longitudinal shaft 12 is mounted in the bearings. rI heshaft inthis instance does not rotate.

On the shaft 12 are fourpaddle-wheels 13, one for each compartment ofthe vat. Each wheel has solid side members 14 and paddles 15 attachedthereto in any suitable manner. The

paddlesl may e modified without departing from the main features of theinvention.

pipe has articular construction of the 2, 1925. Serial No. 60,085.

Mounted on a bracket 16 at one end of the vat is a reversing electricmotor 17,. which drives a longitudinal shaft 18 at the side of thevatthrough gearing 19, shown by dotted lines in Fig. 3. The gearing islocated in an enclosing casing 20.

The shaft 18 has its bearing in brackets 21 secured to the vat, vasshown in Fig. 1. Onv the shaft are bevel gears 22, which mesh with bevelgears 23 on transverse shafts 24 mounted in a bearing 25 .on certainpartitions of the vat. Each shaft 24 drives two paddle-wheels through abevel gear 26 on the shaft, and bevel gear wheels 27 on thepaddle-wheels, so'v that the paddle-wheels rotate upon the fixedshaft12.'

By the above construction, one paddlewheel of each pair rotates in onedirection, while the other paddle-wheel rotates in the oppositedirection, and when the motor reverses, `the direction of movement ofallA paddle-Wheels is reversed. This causes tle` dye liquor in eachcompartment of the vat to circulate in a direction opposite to that inan adjoining compartment and through the perforated. partitions,insuring even dyeing.

The machine is especially adapted for dyeing stockings, and other knitor woven fabrics, and wool and fur felts.

In ordinary practice, when stockings are to be dyed, they are placed inbags-or are otherwise arranged in batches, and each compartment containsa certain number of bags or batches.

lVe claim:

1. The combination in a dyeing machine, of a vat a series of transversepartitions in the vat formingcompartments; a series of paddle-wheels,-one paddle wheel for each compartment, said paddle-wheels being arrangedin pairs; and means for driving the wheels of ,each pair in oppositedirections.

2. The combination in a dyeing machine, of 'a vat; a perforatedtransverse partition inthe vat forming compartments' a paddlewheel ineach compartment; a 7bevel gear wheel on each paddle-wheel; a transverseshaft having a bevel gear wheel. meshing with the gear-wheels on thepaddle-wheels@ and means for driving the transverse Shaft to cause lhepaddle-wheels to rotate in opposite directions.

3. The combination in a dyeing machine, of a vat; a series of perforatedtransverse partitions in the vat; a longitudinal shaft mounted on thevat; two pairs of paddle- Wheels mounted on the shaft, the paddle-Wheels being located in the compartments of the vat; a longitudinalshaft at the side of the vat; means for driving the shaft; andtransverse shafts geared to the longitudinal shaft and to each pair ofpaddle- Wheels.

4. The combination in a dyeing machine, of a vat having a series ofperforated transverse partitions therein; steam pipes in the bottom ofthe vat; a small pipe for admitting coloring matter to the vat, saidpipes having branches opening into the compartments; a longitudinalshaft on the vat; a paddle-Wheel in each compartment and mounted on theshaft; a longitudinal driving shaft at the side of the vat; bevel gearsthereon; transverse shafts having bevel gears at one end meshing withthe gears on the driving shaft and having bevel gears at their oppositeends; and a bevel gear on each paddle-wheel meshing with the gears onthe transverse shaft.
